The Climbing Association of Southern Arizona (CASA) is a 501(c)(3) nonprofit that advocates for local climbers through stewardship, education and partnership with land managers. Founded in 2015, CASA gives back to the local community through collaborative projects. CASA routinely conducts erosion control on Mt. Lemmon trails, removes graffiti at Windy Point, provides education as well as fun, community-building activities, and facilitates Mt. Lemmon Highway cleanups. Through events like these and more, CASA members and supporters pour thousands of volunteer hours into the treasured outdoors, benefiting all users.
